“It is normal hospitality that when somebody asks you to their country and their house that you reciprocate with an invitation so certainly that invitation absolutely still stands.”

The US president owns the Trump International Golf Links and Hotel in Doonbeg in Co Clare.

Mr Varadkar added: “I’m not into golf, so I won’t be playing golf with him if he comes to Doonbeg but perhaps it would be an opportunity for him to potentially visit some of the Irish companies that invest in the US and also perhaps even to see the border between Northern Ireland and Ireland.

“I know that something he has expressed an interest in.”

The Irish Premier said there has been no discussions about such a visit at this stage.
